I want to use arrays with size _CONFIGURE_MAXIMUM_PROCESSORS. Is it
okay if I define the arrays with this size while writing the scheduler
strong APA header file? I am asking this because the value of this
header gets defined at the time the test case runs while the scheduler
gets linked to the test case at the time of linking. So how would it
work?
Do NOT use _CONFIGURE_MAXIMUM_PROCESSORS.
In <rtems/scheduler.h> please use something similar to the EDF scheduler
instantiation:
#ifdef CONFIGURE_SCHEDULER_EDF_SMP
#include <rtems/score/scheduleredfsmp.h>
#ifndef CONFIGURE_MAXIMUM_PROCESSORS
#error "CONFIGURE_MAXIMUM_PROCESSORS must be defined to configure
the EDF SMP scheduler"
#endif
#define SCHEDULER_EDF_SMP_CONTEXT_NAME( name ) \
SCHEDULER_CONTEXT_NAME( EDF_SMP_ ## name )
#define RTEMS_SCHEDULER_EDF_SMP( name ) \
static struct { \
Scheduler_EDF_SMP_Context Base; \
Scheduler_EDF_SMP_Ready_queue Ready[ CONFIGURE_MAXIMUM_PROCESSORS
+ 1 ]; \
} SCHEDULER_EDF_SMP_CONTEXT_NAME( name )
#define RTEMS_SCHEDULER_TABLE_EDF_SMP( name, obj_name ) \
{ \
&SCHEDULER_EDF_SMP_CONTEXT_NAME( name ).Base.Base.Base, \
SCHEDULER_EDF_SMP_ENTRY_POINTS, \
SCHEDULER_EDF_MAXIMUM_PRIORITY, \
( obj_name ) \
SCHEDULER_CONTROL_IS_NON_PREEMPT_MODE_SUPPORTED( false ) \
}
/* Provided for backward compatibility */
#define RTEMS_SCHEDULER_CONTEXT_EDF_SMP( name, max_cpu_count ) \
RTEMS_SCHEDULER_EDF_SMP( name )
#define RTEMS_SCHEDULER_CONTROL_EDF_SMP( name, obj_name ) \
RTEMS_SCHEDULER_TABLE_EDF_SMP( name, obj_name )
#endif
